Solar panels and battery - any real world reccomendations?

Having just googled it, we all pay it through our energy bills, same way we cover bad debt I believe

The GivEnergy charger is not currently compatible with IO, however it is awaiting approval by Octopus.

GivEnergy say all the back end work is done, they are just waiting on Octopus to do their bit. You can already control it using the Octopus R&D site.

Hypervolt is basically in the same situation but perhaps slightly behind.

Cheers mate

My supplier came back and said:

Additional 9.5 battery supplied and commissioned + they will supply the give EV charger £3350 as I'm repeat cx etc..

Think I'm going to book this in, it's a no brainer

I'll keep hold of the charger for now and once it's approved with octo intelligent go I'll get my mate to swap out the ohme

you may need a GE installer to commission it unfortunately. Does the free charger come with installation? If so it may be worth them just installing it and having 2.

Nope

He's checked & confirmed it can be commissioned by yourself, said its a 10 mins process, connecting to wifi and enabling it in the app, I've just checked a vid on YT and you don't need a giv engineer to do it.

Out of interest, I asked if I can have this installed as a second ev charger, it can but it will need approval or something to have a second charger in your home, and may need a fuse uplift. Too much hassle tbh.

I'll keep it till it is approved on IOG or sell it on.

They can install it for £250, my sparky mate will do it for a 12 pack, like he did with the ohme :p

Fair enough, that’s good. I was following the logic that all the other GE kit is installer only.

The DNO approval will be no different to when you got your first charger, you just bung in the form and it’s a formality for the most part. It’s really not a big deal at all and they do it for you if they are installing. The GE charger should have a load management functionality via its CT clamp so there shouldn’t be any main fuse issues.
 
Added 4 x 455w panels to the garden array today, hard going on the higher one.
Birds already pooped on it!.

Just need the sun now ;).

Thoroughly plan your system before you order anything, also make sure that you're battery is connected via a T Class fuse - Victron do a T class Lynx fuse holder now or use stand alone T class fuse holders - mega fuses don't have the AIC rating for LifePo4.
Just been looking into this and it seems from the literature that the T Class Lynx Fuse is M10 only, with the Lynx Shunt only coming in M8 meaning they can't be used together? What would be another way to get the battery monitoring as i do like the T Class. Would i be looking at removing the Lynx Shunt and using something like the SmartShunt's?


Code:
A Lynx distribution system usually consists of a single Lynx Smart BMS module together with a Lynx Class-T Power, Lynx PowerIn or Lynx Distributor. Note that the Lynx Shunt VE.Can is only available with M8 connections and therefore cannot be connecteddirectly to the Lynx Class-T Power, which has M10 connections.
 
No, just the AC near the meter. That’s to measure any excess solar.

If your charger supports multiple CT clamps, on the AC cable feeding any battery storage. Some chargers back back off if they see the battery is draining. CT clamps can’t read DC.

If you are using a hybrid inverter, the CT clamp on the solar/battery doesn’t add much value as it can’t tell if it’s excess solar or it’s drawing from the battery.

Edit: to add to the above, you don’t really want to charge the car from solar unless you are on a FIT contract. Sell to the grid for 15p, buy it back overnight for 7p.

Quick question,

I let intelligent go do it's thing, Plugged the car in the morning, the smart charging saw a number of slots in the day and charged at those times, however it was taking the charge from the givenergy battery instead of the grid :O

Is there a way to prevent charging the car from the battery altogether, I couldn't see anything in the app or portal

I'm using an ohme charger

Or is it a case of just charge 23:30-05:30 which defeats the intelligent part of the tarrif then

Cheers
 
there are two options:

Third party controls for the battery like home assistant. You can use it to ‘watch’ the octopus API and set the battery to charge at the same time as the car for 7p, you then let the solar export for 15p. Profit!

Changes to the way your CTs are set up or how your EV charger is wired into your house. This would make it so the battery can’t ‘see’ the EV charger.

The latter is set and forget but it could cost money if you need to get a spark in.

How is your EV and solar system wired in and where are the CTs located? Pictures would probably help.

I have no idea abount any of this, please advise - is it a good price, is it decent equipment.
Should I ask to change anything, add anything or remove anything?
Our average usage per month over the last 7 months is 865kw - the hot tub has been off since January, so that will be going back on again soon (which will increase this usage).

Many thanks
 
@father-ted top tip, use Notepad++ or something similar, paste the quote and replace all "1 INCLUDED INCLUDED" with "", would make reading it much easier ;)

They get really good reviews on Google, out of 93 reviews only one is one star (just a communication issue), the rest are four or above, Trust Pilot is all five stars, although there are only 9 reviews.
